`which the following is fi iilpecilientien.

My invention relates lo n feed-writer henter end purifier.

The object el" the inveniionis, i'irsnie provide a series of Ushnped tubes, one arm of the tubes receiving the heated steam, which is more er less condensed in practice and voided after ii; has heated the fecd-wnternun rounding the llshnped tubes, the construetion and arrangement being such that the feedoraer enters nd meets the coldest portion of the tube and travels round parallel with the tubes and diecherges opposite the end of the tubes which receive the het steam.

Another object oi my invention is to proF vide zi mud-well, over which the feed-witter is compelled to pese after it has been pfirtinlly heated, where the mettere held in Suspension rire deposited.

The various feenres of my invention elfe fully set forth in thedcscription of the nccompenying drawings, mnkingn peri of this specifiention, in whichi Figure l ie n central vertical longitudinal section of my improvement. Fig. 2 is n see tion on line e: 13, Fig. l. Fig. 3 in en inside elevation of the cop.

C represents :t series of Uehapcd lnbes, the free ends o which nre rigidly secured te the diaphragm 3.

(l represents n partition preferably nnnle in tegrelwith the heed A and snplmrted in the ings iii o the dinphrngin il. This partition censos the sterne to enter-enc end ot the Llshriped tribes and pnss ont. the other.

l? represents n, partition extending een l rnlly through ille heater from ihedinphrnvgin for ward npproxinmtely near the bend of the tn bes :ind is supported upon lues 8 sind il.

il represents the inlet-pipe for nupiilying feedoreier; the outlet-pi pe; K, oscilan-blow This scum may be blown oli l'romtirneto time through the pipe K. The feed-water is snp plied through pipe Il and rises; up and passes round the partition G on its way to lthe ontlei-pipe. 'ihe mechanical impurities held in suspension commence io depositns sonnes the witter connnenees to lient, :ind the pnrti` tien G holds the water beck in the lower portion oli' the heater und prevents it rising rerticnlly npwnrd toward the outlet, buit censos it lo round the partition. in this inovcment the particles held in suspension nre Sepereied and gztthered in the innd-wcll inns also are portions of the miner-nl nnltswhinh nre set free in ille lichting ol the wnler; bnl'. these are largely freed ley the hlgherhcoinp; of the Waiter and deposited npon the shell or pnrtition, (i, which is shown ns readily detnchnble when the heater is inhen npnrl, so that ihis shelf may be cleaned.

It isiinportnnt to prercntlhe senin orlighter 'impurities which lient on lhe top ol` ihe waiter from being carried to the boiler. llenen the outlet l projects :i snl'licient distatnee below the shell of the heater to prevent the senin from being drawn oli' with the i`ec l-wnler- Thus the iced-water is freed el the three iolA lowing impurities: mnd ornnitters held in me chainicnl susi'iension, minernls held in solution, and the scum or lighter portion (hinting en iep of the water.

l have provii'led nn esczipe-pipe N lo carry olif the eondcnsntion of the slenin, which is pure (.listillnd water. ,'lhis muy he connected .t vHaving, described my 'Y l tweeen lip so as to be used for feedwvater or for other purposes. j

, 0 represents the steam-exitpipe, end-F the steam-Supply pipe.

f, This heater is constructed so es to-be readily teken apartl for cleaning` purposes. The bent tubes Amay be removed with the diephregm 3 end the shelf G rendily teken out end cleaned. ."Blowol lpipe M is supplied xo with e, suitable valve, and blow-0E' pipe K is likewise supplied with avnive. These valves may be openenv from time to time to blow oft' the impr: ties.

It willA ."e seen that by the construction of 15 this heater the cold weterie received opposite the steam-exit end of -the tubes. This .more

'i thorounhlycondenses or robe the steam of heat.y It is coin peliedto travel round the shelf end follow up the tubes, graduali y being heet' zo ed, end it is taken ont at thepoint where it is the hottest, thus valways bringing'the hottest water in contact with the hottest steam.

Another advantage arising in making the large settling-chamber is that it serves as n z5 leg to attach the supporting-bese. For this reason -the mud-well is located centrnllyun` der the heater.
